What turbo do you have?

Sounds like the turbo is way to big, the wastegate is way out of adjustment, or you have a boost leak. But thats just what is sounds like to me.

I'm not really familiar w/ 24vs but you should be able to use some thing like a boost elbow, a J-hook, or an adjustable wastegate actuator to control when the wastegate opens.

Yeah i would check for boost leaks first. Cause the factory boost settings on the hy35 and hx35 turbos is 20.5 psi.

Check all of your intercooler piping and couplers then check around the intake on the drivers side of the motor there is a gasket there that could have blow out.

I'm not 100% sure, but most Cummins powered trucks I've seen, stock, will boost to around 18psi. You may have a pin hole in a boot, or a blown one.

Use the old Ether trick: While idling, just spray little amounts of ether, or CRC, around your boots--if it revs up on it's own, you have a leak.:Thumbup:

your not giving it enough fuel to create the boost I think you want...theres no way a power puck is going to do that for you...when you take off what are your RPMs? it may just be simple lag? do you have a tag for model number or anything for the turbo?

I think the Power Puck does mostly timing, you have to much air and not enough fuel. You need at least a Edge Comp IMO. And may I ask why you want so much boost?
